Beschreibung
Zusammenfassung:	The present invention relates to an contactless electronic system configured for contactless communications with a reader over an electromagnetic field and comprising a power supply, a current monitor, a processing system comprising a hardware processor configured for performing operations, a dynamic extra current loader and a clock generator, wherein :- said current monitor is configured for determining maximal current Imax that can be provided by the power supply to the processing system from the electromagnetic field,- said current monitor is configured for comparing, during an execution phase of said hardware processor, said determined maximal current Imax and a current drawn by the processing system Iplatform,- said dynamic extra current loader is configured for loading an extra current lextra equal to Imax-Iplatform when the current drawn by the processing system Iplatform is lower than the determined maximal current Imax.
